Ok i understand to some extend that cold air is more dense and that you get more volumn of air into chamber as a result. I don't have CAI yet but planning for one if get convinced.
So this weekend when i looked under the hood, it seems to me that maxima's air intake is on top of radiator (at the very front just next to grill) and so when the car is running you are getting the cold fresh air anyway??? It might be different on ideling thought. how does this differ when you get it from above the tire?????
Does CAI has less air obstruction in the filter?? how you get HP?
